Check Digit Verification of cas no

The CAS Registry Mumber 77463-55-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,6 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77463-55:
(7*7)+(6*7)+(5*4)+(4*6)+(3*3)+(2*5)+(1*5)=159
159 % 10 = 9
So 77463-55-9 is a valid CAS Registry Number.
